Project history
Engineered real-time multilingual translation capabilities into the Mission Critical Push-to-Talk application. Architected Inter-MCX Push-to-Talk protocols across legacy and modern server platforms for secure multi-agency interoperability. Migrated server provisioning workflows from RASA chatbots to a modern MCP-based agentic AI architecture (Google ADK). Directed the Secure Software Development Lifecycle for high-availability communication stacks.
Led architectural performance tuning for Security Edge Protection Proxy (SEPP) and 5G Core functions, optimizing high-volume signaling across next-generation infrastructure. Directed comprehensive interoperability engagements across tier-1 RAN, handset, and 5G core vendors. Designed high-throughput test automation libraries, increasing regression coverage and stress-testing throughput for core procedures.
Designed high-performance 5G core protocol stacks conforming to 3GPP specifications across NAS, NGAP/S1AP, and HTTP/2 SBI interfaces. Engineered high-capacity gNodeB/eNodeB and 5G/4G UE non-radio simulation interfaces for mission-critical core load validation. Implemented and optimized 4G EPC nodes (SGW, PGW) for carrier-grade benchmarking. Developed protocol test tools, network sniffers, and custom SSL/TLS traffic decryption modules. Built mobile-based validation applications on Android and iOS to automate LTE field testing and radio performance audits.
